Step-by-step explanation:

area of square is (side)2 .

so 76×76=5776

Answer 2

Answer:

Ans. (a) We know that,

Area of a rectangle = Length Breadth

Area of the floor of kitchen = (Length Breadth)

= (220 180) square cm.

Also, we know that

Area of a square = Side Side

Area of one tile = (10 10) square cm

Number of tiles required

=

=

= 22 18 = 396

(b) The fencing of a square garden is 20 m in length. How long is one side of the garden?

Ans. (b) We have, Perimeter = 20 m

Side = Perimeter

Side = = 5m

(c) A thin wire 20 centimetres long is formed into a rectangle. If the width of this rectangle is 4 centimetres, what is its length?

Ans. (c) We have, Perimeter = 20 cm and Breadth = 4cm

Length = Perimeter – Breadth

Length = 20 cm – 4cm = 6 cm

= 10 cm – 4 cm = 6 cm

(d) A square carom board has a perimeter of 320 cm. How much is its area?

Ans. (d) We have, Perimeter = 320 cm

Side = Perimeter

Side = 320 cm = 80 cm

Area = Side Side

= (80 80) square cm = 6400 square cm
