Question

the area of triangle is equal ro area of square of 30cm .Find the length of the base of the triangle if its altitude 90cm​

Answer 1

Answer:

The Correct Answer is 20 cm

Step-by-step explanation:

Area of Square is: Side cm X Side cm

= 30 cm X 30 cm

= 900 $cm^{2}$

Therefore, Area of Triangle is also = $900 cm^{2}$

Altitude of Triangle is: 90 cm

Area of Triangle is =  1/2 X Base X Altitude

900 = 1/2 X Base X 90

10 = 1/2 X Base

Base = 20 cm

Answer 2

Answer:

${(30cm)}^{2}$

${900cm}^{2}$

$\frac{1}{2} \times b \times 90cm = 900 {cm}^{2}$

$b = \frac{900 {cm}^{2} }{45cm}$

$20cm$
