Question

27) The area of rectangle is equal to the area of a circle with circumference equal to 220m. what is the length of the rectangle if its breadth is 50 m? 56 mb. 83 m c. 77 m d. 69 m d. none of these a.​

Answer 1

Answer:

length = 77m

Step-by-step explanation:

area of rectangle = length × breadth

area of circle = π r^2

circumference = 2πr

220 = 2× 22/7 × r

(220×7)/2×22 = r

35 = r, where r is the radius

Ar of rectangle = Ar of circle

length × breadth = πr^2

length × 50 = 22/7 × 35 ×35

length = (22×35×35)/ (7×50)

length = 77m
