Question

Find the area and perimeter of a rectangle, whose :
length = 1m 30cm and breadth = 70 cm​

Answer 1

Answer:

1m = 100cm

1m 30cm = 100+30 = 130cm

Length = 130cm

Breadth = 70cm

Perimeter of rectangle = 2( l + b )

P = 2( 130 + 70 )

P = 2( 200 ) = 400 cm

Area = l × b

A = 130 × 70

A = 910 cm²

Answer 2

Answer:

Area=91m & Perimeter=142m 6cm

Step-by-step explanation:

Area

Area of rectangle is = length * Breadth

                                 = 1m 30cm * 70cm

                                 = 91m

Perimeter

Perimeter of rectangle = 2 *(length+Breadth)

                                     = 2 * (1m 30cm + 70cm)

                                     = 2 * 71m 3cm

                                     =  142m 6cm
