Question

In the given grid if each square is 1cm2. The area of the shaded portion shown in the grid is close to... (a) 13 cm² (b) 20 cm² (c) 49 cm² (d) 10 cm²​

Answer 1

Answer:

d) 10cm²

Explanation:

Given,

Each square in the grid measures 1cm²

Find the area of shaded region.

Following the figure,

we see that there are 6 squares and 6 partially shaded squares.

Area of the 6 shaded region:

→ 6 × 1

→ 6cm²

Let's assume the partially shaded region as ½ of 1cm²

So, if there are 6 of them. we could count 6 × ½ = 3 squares.

Now,

Area of the shaded region:

→ Area of the shaded squares + Area of the partially shaded squares.

→ 6 + (3*1)

→ 6 + 3

→ 9cm²

Approximately, it's close to 10cm².

Required answer: 10cm²
