Answer 2

The area of the region bounded by the rectangle​ is 490 sq cm

Solution:

Given that,

Length : breadth = 5 : 2

Let the length be 5x

Let the breadth be 2x

Perimeter of rectangle = 98 cm

2(length + breadth) = 98

length + breadth = 49

5x + 2x = 49

7x = 49

x = 7

Thus,

Length = 5x = 5(7) = 35

Breadth = 2x = 2(7) = 14

Find the area of rectangle

Area of rectangle = length x breadth

Area of rectangle = 35 x 14

Area of rectangle = 490

Thus area of the region bounded by the rectangle​ is 490 sq cm
