Question

Find the perimeter, area and length of the diagonal of the rectangle when length =24m width is 7m

Answer 1

Answer:

Perimeter= 2(24+7)

= 2×31 = 62m

Area= (24×7)m² = 168m²

Diagonal= √(24²+7²) = √(576+49) = √625 = 25m

Step-by-step explanation:

Answer 2

Answer:

l = 24cm     b = 7m = 700cm

Perimeter = 2 ( l + b )

                = 2 ( 24 + 700 )

               = 2 ( 724 )

               = 1,448cm

Area = l x b

        = 24 x 700

        = 16,800‬cm

As a diagonal bisects a rectangle into 2 right angled triangles , we can find the value of diagonal by pythagorous theorem,

(length)^2 + (breadth)^2 = (diagonal)^2

(24)^2 + (700)^2 = (diagonal)^2

576 + 490000 = (diagonal)^2

(diagonal)^2 = 490,576‬

diagonal = 700.41
