Question

The width of the triangle is 3/4 the length. The perimeter is 252cm. What is the width of the triangle.

Answer 1

Answer:

C).  54 cm.

Step-by-step explanation:

I think you mean a rectangle .

If the length is x then the width = 0.75x   (because 3/4 = 0.75).

Perimeter = 2*length + 2*width.

252 =  2x + 2*0.75x

252 = 2x + 1.5x

252 = 3.5x

x = 252 / 3.5

= 72  which is the length,

The width = 3/4 * 72

= 54 cm.
