Question

the area of a parallelogram lawn in the save as the area of an 18 m long square. if the length of the rectangular lawn is 27 M, find its perimeter.

Answer 1

Length of square = 18 m

Area of square = side ×side

18×18=324 square metre

Length of rectangular lawn = 27 m

Breadth=?

Area = l×b

324= 27×b

Breadth= 324/27=12

B= 12m

Perimeter of rectangle = 2(l+b)

2×(27+12)

2×39=78 perimeter

Therefore the breadth of the rectangular lawn is 12m and perimeter is 78m
