Question

Which has the larger area and by how much - a rectangle with length 25cm and breadth 35cm or square of side 30cm?​

Answer 1

Answer:

Perimeter of rectangle = perimeter of square =80 cm

⇒2(l+b)=45=80

⇒S=

4

80

=20 cm;2(l+b)=80

⇒l+b=40 cm - (1)

difference m areas = 100 cm

2

5

2

−(lb)=100

(20)(20)−(lb)=100

⇒lb=300 - (2)

From (1) and (2)

30+10=40;3×10=l×b

⇒l=30 and b=10

sides of rectangle are 30,10 cm

Answer 2

Answer:

Square has 25 sq cm larger area than rectangle.

Step-by-step explanation:

Area of rectangle= L×B

= 25×35 = 875 sq cm

Area of Square = a^2 = 30×30

= 900 sq cm

So square has larger area.

by= 900 - 875

= 25 sq cm
