Question

A rectangle has an area of 235.2m2.

One of the sides is 2.8m in length.
Work out the perimeter of the rectangle.

Answer 1

173.6 m

Explanation:

Perimeter of rectangle= 2* length + 2* width

Area = 235.2m²

Length= 2.8

Area of rectangle: length*width

So: 2.8*width= 235.2m²

width= 235.2/2.8= 84

Use the formula for perimeter of rectangle

So: 84*2 + 2.8*2

Perimeter= 173.6m
