Question

Lenght of rectangle feild is 15m and diagonal is 17m find its area and perimeter

Answer 1

Hi ,

Length of the rectangle field = l = 15m

diagonal ( d ) = 17 m

Let the breadth= b m

b² = d² - l²

=> b² = 17² - 15²

=> b² = ( 17 + 15 )( 17 - 15 )

=> b² = 32 × 2

=> b² = 64

b = 8 m

i ) Area of the rectangular field = A

A = lb

A = 15m × 8m

A = 120 m²

ii ) Perimeter ( P ) = 2( l + b )

P = 2 ( 15m + 8m )

P = 2 × 23m

P.= 46m

I hope this helps you.
