Question

A teacher drew a triangle of 8cm height and 18cm base. Now he wants to
draw a square whose area must be the twice that of the triangle. Calculate the
length of the each side of the square that he has to draw.

Answer 1

Answer:

side of the square will be 12 cm

Step-by-step explanation:

area of triangle = 1/2(base)(height)

therefore

area of this triangle = 1/2(18)(8) = 72 cm²

given area of the square = 2 times of triangle

=>area of square = 72×2= 144cm²

side of square = √area of square

=> side of square = √144 =12cm

Answer 2

Answer:

36cm

Step-by-step explanation:

Area of triangle=B×H/2

=18×8/2 = 72 cm²

Area of square= Double of area of triangle

72×2 = 144 cm²

Length of each side of the square=

144/4 =36 cm
