A right angled trapezoid is 8.4cm in upper bottom and 15.6cm in lower bottom. Cut out the largest triangle in the right angled trapezoid, and the remaining area is 37.8cm square. What is the area of the original trapezoid?

A right angled trapezoid is 8.4cm in upper bottom and 15.6cm in lower bottom. Cut out the largest triangle in the right angled trapezoid, and the remaining area is 37.8cm square. What is the area of the original trapezoid?

As shown in the figure above, the height of right angled trapezoid H = 37.8 × 2 △ 8.4 = 9 (CM), the original trapezoid area is: (8.4 + 15.6) × 9 △ 2 = 108 (cm2); answer: the original trapezoid area is 108 cm2

A right angled trapezoid has an upper bottom of 8.4 cm and a lower bottom of 15.6 cm. Cut out the largest triangle in the right angled trapezoid, and the remaining area is 37.8 square cm. What is the area of the original trapezoid

37.8x2 divided by 8.4 = 9 cm high
(8.4 + 15.6) x9 divided by 2 = 108 square centimeters
