Question

Find the area, perimeter and diagonal of a rectangle whose adjacent sides are 1.5m and 200cm respectively.

Answer 1

Answer:

Step-by-step explanation:

Sides of the rectangle are 2.5m and 200cm

200cm = 200/100 = 2m

here,

length,  l = 2m

breadth,b= 1.5m

Area = lxb

       = 2x1.5

       = 3m² = 3x100x100cm =30000cm²

perimeter = 2(l+b)

               = 2(1.5+2)

               = 2x2.5

               = 5m = 5x100cm =500cm

diagonal² = l²+b²

          d² = 2²+ 1.5²

              = 4+2.25

              = 6.25

          d  =√6.25

              = 2.5m = 2.5x100cm = 250cm
