heya it's Aastha....
◆ area of∆ = 1/2 × b × h

220. = 1/2 × b× 11

220×2/11 = b

40 cm. = b .

Answer:

Hence, base of triangle will be 40 cm

Step-by-step explanation:

In context to question asked,

We have to determine the value of base of triangle.

As per data given in the question,

We have,

Area of triangle = 220 Sq. cm

Height/Altitude of triangle = 11 cm

As we know that,

Triangle is a three sided figure,

Sum of all angles of the triangle is 180 degree.

The area of triangle can be determined by using formula Area = \frac{1}{2} \times base \times Height

So, for determining the base of triangle we will put the value of height/Altitude and area given in the question in above formula,

Thus we will get it as,

Area =\frac{1}{2} \times b \times h\\=>220 = \frac{1}{2}\times b \times 11\\=>b = \frac{220 \times 2}{11}\\=>h = 20 \times 2 = 40\:cm
