Find the area of the shaded portion The image contains a problem involving the calculation of shaded areas within a geometric figure. Here's the transcription:---The shaded areas of the figure may be found by subtracting the area of the unshaded portion from the total area of the figure. Use this approach to find the area of the shaded portion.A geometric figure is illustrated, which includes two congruent triangles within a rectangle.**Dimensions:**- The length of the top side of each triangle is 55 cm.- The height from the top of each triangle to the base of the rectangle is 26 cm.- The total height of the rectangle is 77 cm.**Figure Details:**The image shows a rectangle with two congruent triangles at the top, effectively forming spaces within the rectangle.---To calculate the shaded area, one must:1. Calculate the total area of the rectangle.2. Calculate the total area of the two triangles.3. Subtract the area of the triangles from the area of the rectangle.The interface allows a user to input the area value and select units from options: cm³, cm, cm².

From the given figure, Area of shade portion= area of rectangle – area of both triangle To calculate the area of rectangle, Area of rectangle=77×55+55=77×110=8470 cm2 To calculate the area of both triangle, Area of both triangle=12×base×Height+12×base×Height=12×55×26+12×55×26=715+715=1430 cm2To calculate the area of shaded portion, Areaofshadeportion=areaofrectangle--areaofbothtriangle=8470-1430=7040 cm2 Hence the area of shaded portion is 7040 square cm
