Question

The perimeter of a rectangular plot is 378
m and it's breadth is 21 m. Find the length
and area of the plot.
​

Answer 1

Step-by-step explanation:

perimeter of rectangle is = 2×(l+b)

378 = 2×(l+21)

378/2 = l+21

189 = l+21

189-21 = l

168 = l

area of plot = length × breadth

= 168 × 21

= 3528 m²
