A. The perimeter of a right triangle is given by summing all the sides.

4x + 2 + 7x + 7 + 5x - 4

x + 3 + 2x - 5 + x + 7

b. I think you have to combine like terms of the expressions.

16x + 5

4x + 5

c.

Large triangle: 4(3) + 2 + 7(3) + 7 + 5(3) - 4 = 12+2+21+7+15-4 = 53

Small triangle: 3 + 3 + 2(3) - 5 + 3 + 7 = 3+3+6-5+3+7 = 17

A rectangular garden has an area of 46 1/2 square feet. If the garden is 7 1/2 feet long, how many feet wide is it?

Ierofanga [76]

Answer:

The answer is 6 1/5 feet in width.

Step-by-step explanation:

Since the formula for area is wl or width x length, we can utilize our reversive property to find our width by dividing the Area we are given by our length, giving us the missing width in return. Dividing 46.5 square feet by 7.5 feet gives us 6.2 feet, or 6 1/5 feet.

Hope this helps!
