Question

I need help with this one also....and one more after this Please...

Answer 1

Answer:

80cm²

Step-by-step explanation:

first we will find the area of the rectangle

area of rectangle= length× breadth

= 13×8= 104 cm²

area of shaded region= area of rectangle-unshaded region

unshaded region= the four triangles

we know that the area of each of the triangles is same so we will find the area of one and multiply it by four

area of triangle= 1/2 × b× h

= 1/2×4×3= 6cm²

area of four triangles= 6×4=24²

area of shaded region=area of rectangle-area of unshaded region

= 104-24

= 80 cm²
