Answer :

Given: Side of the square park = 60 m

Length of the rectangular park = 90 m

Area of the rectangular park = Area of the square park

Or, l×b = side × side

Or, 90× b = 60×60

Or, b = \(\frac{60×60}{90} \) = 40m

Hence, the required breadth = 40 m.

- Q.1 The length and the breadth of a rectangular piece of land are 500 m and 300 m respectively. Find (i) its area (ii) the cost of the land, if 1\( m^2 \) of the land costs Rs. 10,000
- Q.2 Find the area of a square park whose perimeter is 320 m.
- Q.3Find the breadth of a rectangular plot of land, if its area is 440\( m^2 \)and the length is 22 m. Also, find its perimeter.
- Q.4 The perimeter of a rectangular sheet is 100 cm. If the length is 35 cm, find its breadth. Also find the area.
- Q.6 A wire is in the shape of a rectangle. Its length is 40 cm and breadth is 22 cm. If the same wire is rebent in the shape of a square, what will be the measure of each side. Also find which shape encloses more area?
- Q.7 The perimeter of a rectangle is 130 cm. If the breadth of the rectangle is 30 cm, find its length. Also find the area of the rectangle.
- Q.8 A door of length 2 m and breadth 1 m is fitted in a wall. The length of the wall is 4.5 m and the breadth is 3.6 m (Fig). Find the cost of white washing the wall, if the rate of white washing the wall is ? 20 per\(m^2.\)
