The area of a triangle is 30 square inches. What is the length of the base if the height is 6 centimeters?

x = 10 cm

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = bh ( b is the base and h the perpendicular height )

Here b = x, h = 6 and A = 30 , then

× 6 × x = 30

3x = 30 ( divide both sides by 3 )

x = 10

51840000 cm 2

step-by-step explanation:

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to
