Actually welcome to the concept of the Areas and Volumes,

Here we calculate the area of a Trapezoidal Surface,

Area of a Trapezium is

A = 1/2 (a+b) *h

here, a=60 , b= 30 , h= 14

A = 1/2(90)*14

A = 630 in^2

Answer 2

Answer: 630 square inches.

Explanation:

The formula to find the area of a trapezium is given by :-

`A=(1)/(2)h(a+b)` , where h is the height and a & b are the measures of parallel sides.

According to the given figure , we have

a=30 in. b= 60 in. and h = 14 in.

Substitute all the values in the above formula, we get

`A=(1)/(2)(14)(30+60)\\\\\Rightarrow\ A=(7)(90)=630`

Hence, the area of the table = 630 square inches.
