Question

Q1. The area of a square is 105 m². Find (i)the length (ii) the perimeter of the square to 3 significant figures?​

Answer 1

Answer:

Two poles stand on the ground at a distance of 20m and 50 m respectively from a point A on the ground, the taller pole at 30 m from smaller pole. A cable originates from the top of the taller pole, passing on the other pole ends on a hook at point A. If the length of the cable is 100 m, how much of it lies between the the two poles? (a) 50m

(b) 40 m

(C) 60 m

(d) 80 m

(d) 80 m

Answer 2

i) area of sq. = 105{m}^{2}

formula ,

A = {a}^{2}

105 = {a}^{2}

a = \sqrt{105}

a = 10.247 m

ii) formula ,

p = 4a

p = ( 4 \times 10.247)m

p = 40.988 m.

hope it helps .. !!
