I'm pretty sure it's (1/2×50) +7
and (1/2×100)+7
others don't work.

The perimeter of a rectangle is 102 inches. The length is 5 inches greater than the width.
Mazyrski [523]

Answer:

w = 23

l = 28

Step-by-step explanation:

w = width

l = w+5

P = 2 (l+w)

102 = 2( w+5+w)

102 = 2(2w+5)

Divide each side by 2

51 = 2w+5

Subtract 5

46 = 2w

Divide by 2

23 = w

The width is 23 and the length is 23+5 = 28

Jerome won a school competition to design a mural for the cafeteria wall. Jerome’s scale drawing was 12 inches wide and 9 inches
svetlana [45]
The actual mural will be 15 feet tall.

To find the height of the mural, we first need to find the scale by dividing Jerome's scale drawing's measurements from the mural's measurements.

Before we do that, we need to make sure our units are the same. Jerome's scale drawing is measured in inches, and the mural is measured in feet. To keep the numbers whole, I'm going to convert the mural's width from feet to inches by multiplying it by 12.

20 × 12 = 240

Now that our units are the same, we can divide Jerome's scale drawing's width from the mural's width to find the scale.

240 ÷ 12 = 20 

The scale of Jerome's scale drawing to the mural is 1:20. This means that the mural's measurements are 20 times Jerome's scale drawing.

Now, to find the height, or how tall the actual mural will be, you multiply the height of Jerome's scale drawing, 9 inches, by the scale, 20.

9 × 20 = 180 inches

Since the question is asking how tall the mural will be in feet, you divide 12 from 180 to find the number of feet in 180 inches.

180 ÷ 12 = 15 feet

The actual mural will be 15 feet tall.

Joel measured the middle school. The gym, which is 51 feet wide in real life, is 34 inches wide in the drawing. What scale did J
Dominik [7]
51 feet in real life is represented by 34 inches on paper.

51 feet : 34 inches

34 inches : 51 feet.

Note: 1 feet = 12 inches.

34 inches : 51 feet

34 inches : 51 * 12 inches

34 : (51* 12)

1 : (51 * 12 ) / 34

1 : 18

So the scale of the drawing is  1 : 18.

Hope this helps.
