Question

Find the sides of square with the given area but without root.
(a) Area =
(c) Area =
64 square m
17.64 square cm
(b) Area = 43.56 square cm
(d) Area 81 square cm​

Answer 1

Answer:

• If area = 64 sq. m then side = 8m
• If area = 17.64 sq. cm then side = 4.2 cm
• If area = 43.56 sq. cm then side = 6.6 cm
• If area = 81 sq. cm then side = 9cm

Step-by-step explanation:

1) Area = 64 sq. m

Area of square $= (side)^2$

$(side)^2 = 64\\side = \sqrt{64} \\side = 8 m$

2) Area = 17.64 sq. cm.

Area of square $= (side)^2$

$(side)^2 = 17.64\\side = \sqrt{17.64} \\side = 4.2cm$

3) Area = 43.56 sq. cm.

Area of square $= (side)^2$

$(side)^2 =43.56\\side = \sqrt{43.56} \\side = 6.6cm$

4) Area = 81 sq. cm.

Area of square $= (side)^2$

$(side)^2 = 81\\side = \sqrt{81} \\side = 9cm$
