Question

the area of a triangle is equal to that of a square whose each side measures 60 find the side of triangle whose corresponding altitude is 90m​

Answer 1

Answer:

80 cm

Step-by-step explanation:

Side of square = 60 cm

Area of square = a² = 60² = 3600cm²

Area of square = area of triangle

so

area of triangle = 3600cm²

Height of triangle = 90 cm

$\frac{1}{2} \times b \times h = 3600 \\ \\ \frac{1}{2} \times b \times 90 = 3600 \\ \\ b = 3600 \times 2 \times \frac{1}{90} \\ \\ b = 80 \: cm$
