Question

find the area of the following composite figure ​

Answer 1

Answer:

Step-by-step explanation:

ar . of triangle = 1/2bh

ar of rectangle = lb

area of fig.=area of rectangle + area of big triangle + area of triangle                                

   =1/2*5*3 + 10*5 + 1/2*4*5 cm^2                

   =7.5 + 50 + 10 cm^2                              

   =67.5 cm^2

Answer 2

Area of the given figure is 67.5 cm²

Given:

A figure with dimensions.

To Find:

The area of the figure.

Explanation:

Area of triangle = $\frac{1}{2} bh$

Area of rectangle = (l × b)

Area of fig of the given figure = (Area of rectangle + Area of bigger Δ +                       Area of smaller Δ)                            

= $\frac{1}{2}$ × (5×3) + (10×5) + $\frac{1}{2}$ × 4 × 5cm²              

= 7.5 + 50 + 10 cm²                            

= 67.5 cm²
