Maths question

Find the area of the figure below. The steps have equal depths and heights.



Basically to find the area of such figure, we need to "break " the figure up into rectangles or squares so that we can find the area of rectangles or squares.

Formula for area of rectangle : length x breadth



Since the depth of the steps are equal ==> 90 divide by 3 = 30

Area of A= 105 x 30 = 3150

Since the height of the steps are equal ==> 105 divide by 3 = 35

Height of Rectangle B = 105-35 = 70

Area of B = 70 x 30 = 2100

Area of C = 35 x 30 = 1050

Area of figure = Area of A + Area of B + Area of C
= 3150 + 2100 + 1050
= 6300


Ans: 6300 cm2
