Question

A rectangular piece of land has one side that measures 1500 m if the perimeter is 9 km, calculate the measurement of the remaining sides

Answer 1

Let 1500 m be the length (l) of the rectangular land.

Perimeter = 9 km

= 9000m

Also, Perimeter = 2(l+b)

9000 = 2 (1500 + b)

9000/2 = 1500 + b

4500 = 1500 + b

4500-1500 = b

3000 = b

Therefore, the measure of the remaining sides are 3000m, 1500m, 3000m (opposite sides of a rectangle are equal)
