How many square inches of sheet metal are used to make the vent transition​ shown? (The ends are​ open.)

Area of the metal sheet required = 364 square inches

Step-by-step explanation:

Area of the metal sheet required = Surface area of the lateral sides of the vent transition

Since, lateral sides of the vent is in the shape of a trapezoid,

Therefore, surface area of the vent = 4(Surface area of one lateral side)

                                                           =

Here, and are two parallel sides and is the distance between these parallel sides.

Surface area of the vent =

                                         = 364 square inches

Therefore, area of the metal sheet required = 364 square inches

answer: the answer is 110

emily solved for a part when she should have solved for the whole. 875,000 should be the numerator of the equivalent ratio. 70 x 12,500 is 875,000. so the answer is 100 x 12,500 which is 1,250,000.
