Question

Find the breadth of a rectangle whose length is 85 cm and perimeter is 280 cm. Answer fast please

Answer 1

length of rectangle = 85 cm

perimeter = 280 cm

let the breadth of rectangle = x

formula of perimeter = 2(l + b)

280 = 2 ( 85 + x )

280 / 2 = 85 + x

140 = 85 + x

140 ‐ 85 = x

x = 55

:) breadth is 55
