Question

Piyush is a landscape designer and is trying to create a garden. Piyush wants to

design the garden so that it resembles a square contained which is in the rectangle.

The modeled area of square is given by

expression 2x2

+ 5x − 2 and area of rectangle

is given by 8x2

− 7. He wants to

figure out area between rectangle and square

available for planting some plants. Which of

the following expression represents the area

Piyush will have available for planting?​

Answer 1

1). 4+4+4=12cm

2). perimeter=2(l+b)

2×50+30

=2×80

=160cm

3). area = s×s

40×40

=1600cm

4). circumference= 2πr

= 2×22/7 ×14

=88 cm

5). figure not given

6). circumference= 2πr

66 = 2×22/7×r

66 ×7 = 44r

= 472=44r

radius = 10.5 cm

7). B) area =s×s

12×12= 144 cm

perimeter= 4×s

= 4×12

=48 cm

8).
