The length of a rectangle is five times its width.
Vera_Pavlovna [14]

Answer:

72

Step-by-step explanation:

l = 5w

A = l*w

180 = 5w *w

180 = 5w^2

Divide each side by 5

180/5 = 5w^2 /5

36 = w^2

Taking the square root of each side

sqrt(36) = sqrt(w)^2

6 =w

l = 5w = 5*6 = 30

The perimeter is

P = 2(l+w)

P = 2(6+30) = 2(36) = 72

If you know the area and the height of a triangle, how can you find the base.?
sveta [45]

Answer:

b = 2A/h

Step-by-step explanation:

The formula for area of a triangle is

A = 1/2 bh  where b is the base and h is the height

We want to find the base

Multiply each side by 2

2A = 2*1/2 bh

2A = bh

Divide each side by the height

2A/h = bh/h

2A /h = b

b = 2A/h
