Question

Find the perimeter of a rectangle whose area is 8whole 2/3 sqcm and length is 5whole 7/9cm.​

Answer 1

Area of rectangle = l × b

Area = 8 × 2/3 sqmm

L = 5 × 7/9 mm

B = ?

26/3 = 52/9 × b

b = 26/3×9/52

b = 78/52

So now we can find perimeter of rectangle.

perimeter of the rectangle = 2 ( l × b)

➡2(52/9+78/52)

➡2(1703/234)

➡3406/234

So the perimeter of rectangle is 3406/234
