the surface area of a pyramid is 85 square meters the side length of the base is 5 meters what is the slant height

6 meters

Step-by-step explanation:

is the formula that you use

h=vertical altitude and

a=side length of the base

Vertical altitude (h) and and the slant height form a right triangle with the slant height being the hypotenuse

where s=slant height

s=6 meters

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
