Question

The figure below is formed by 8 identical rectangles and 1 triangle. Find the

Answer 1

Answer:

Step-by-step explanation:

Base of triangle  = length of the rectangle

Since, all are identical rectangles,

Length of a rectangle= 36/2 = 18 cm

Base of triangle = 18 cm

Height of triangle = length of the rectangle + width of the rectangle

Width of 6 rectangles = 36

Width of 1 rectangle = 36/ 6 = 6 cm

Height of the triangle = 18 + 6 =  24 cm

Area of the shaded triangle = $\frac{1}{2}base*height$

                                              = $\frac{1}{2}*18*24$

                                              = 9 * 24

                                             = 216 cm²
