Find the area of the triangle

The area of the triangle is:

You can easily find the area of a triangle using the formula:

Where h is the height of the triangle, and b the base.

Looking at the figure we can see that h = 7, but we need to discover the base, we know that the base is:

Where:

Therefore, our base length is:

Then we can just apply the formula for the area:

Any doubt? Write it in the comments and I'll help you

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
