Work out the area of the rectangle

Mathematics
1 answer:
Anna007 [38]2 years ago
8 0

Answer:

48 cm²

Step-by-step explanation:

Let's call the width and height of the rectangle w and h.

w / h = 3 / 4

2w + 2h = 28

Solve the system of equations with substitution.

w = 3/4 h

2 (3/4 h) + 2h = 28

3/2 h + 2h = 28

7/2 h = 28

h = 8 cm

So the width is:

w = 3/4 (8)

w = 6 cm

So the area is:

A = wh

A = 48 cm²

A man is 6 feet tall. At 1:00, he casts a shadow that is 18 inches long. A nearby tree is 32 feel tall. At the same time of day,
sergejj [24]

The answer of this would be 8 feet long.

If you take 6 feet and put that into inches, the man would be 72 inches tall. at one oclock he casts a shadow that is 1/4 of his length. so if we take this knowledge to the tree and divide 32 feet by 4, we get 8 feet long

answer: 8 feet

Someone anyone please please I am begging help me
zaharov [31]

Answer:

Step-by-step explanation:

Since (8x-20) and (3x+2) are two sides of the angles on one plane, we can structure them into an equation to find x.

(8x-20) + (3x+2) = 180

We want x to be on one side and all the numbers to be on the other. But first, we must combine our two problems.

-20 + 2 = -18; 8x + 3x = 11x

So now our equation is:

(11x-18) = 180

In order to move our numbers to one side and leave our x's on the other, we must inverse our additions/subtractions/etc.

180 + 18 = 199

11x = 199

199/11 = 18.1

x=18.1!

Regards!
