Question

A rectangle has a perimeter of 320m and the length is 3 times its width .Find the dimensions hence find the area​

Answer 1

Answer:

l = 120 m , b = 40 and area = 4800 m sq.

Step-by-step explanation:

perimeter= 2 [ l+ b]

320 / 2 = l + b

160 = 3b + b

160 = 4b

b = 40 m

therefore length = 120 m and breadth  =40 m

area  = l * b

120 * 40

4800 m sq.
