Question

A rectangle has an area of 75.2m2.One of the sides is 0.8m in length.Work out the perimeter

Answer 1

Answer:

Given that,

Area of the rectangle=75.2m²

one of the side =0.8m

area of rectangle=l×b

75.2=0.8×b

b=75.2/0.8

b=752/8

b=94m

Answer 2

Answer:

length of rectangle:0.8m

area of rectangle : 75.2m sq.

breadth of rectangle:area /length

                               =75.2/0.8

                               =94m

therefore the perimeter of rectanmgle=2(length+breadth)

                                                                  2(0.8+94)  

                                                                   2(94.8)

                                                                   189.6
