What is the area of this trapezoid?
a. 175 in2
b. 140 in2
c. 129 in2
d. 85 in2

B. 140 in^2

Step-by-step explanation:

A = 1/2(b1 +b2)(h)

=1/2(15 + 4 + 15 + 6)(7)

=1/2(40)(7)

= 140 in^2

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

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
