Question

A wire when bent in the form of an equilateral triangle encloses an area of 36√3 cm²,
Find the area enclosed by the same wire when bent to form:
(i) a square, and
(ii) a rectangle whose length is 2 cm more than its width.​

Answer 1

Answer:

area = 6x3 = 18

area of triangle = 1/2 x base x height

18 x 2 = base x height

36 = base x height

base = 36 x height

Answer 2

Step-by-step explanation:

side of the triangle =12cm

perimeter =36m

i)perimeter of square=4a=36

a=9,area=a²=81

ii)2(L+L-2)=36

L=10,W=8

area=8×10=80
