Question

What is the area of this shape? the answer isn't 92 cm squared

Answer 1

80cm^2

Step-by-step explanation:

Okay to do this, it's often better to find the area of each shape separately.

Let's start with the top rectangle:

4cm*7cm = 28cm^2

Bottom rectangle:

to find the length of it, we just add 3cm and 7cm which = 10cm

so:

10cm*4cm = 40cm^2

And finally the triangle:

to find the bottom side: 13cm - 7cm - 3cm = 3cm

to find the height: 4cm + 4cm = 8cm

so:

8cm*3cm*/2 = 24cm/2

= 12cm^2

Now we add them all up:

28 + 40 + 12 = 80cm^2

Answer 2

Corrected Question:

[ Refer to the above attachment ]

Solution:

In the given figure there are two shapes:

1. A Rectangle
2. A Triangle

First, we have to find the area of Rectangle ABGF & DCGE. After that, area of triangle CHB.

1) Area of Rectangle ABGF:

As, we know:

Formula for Area :-

★ Length × Breadth ★

where,

• Length = FA = 4cm
• Breadth = GF = 10cm ( 7+3 )

➝ 4 cm × 10 cm

➝ 40 cm²

Hence, the area of Rectangle ABGF is 40cm².

2) Area of Rectangle DCGE:

As, we know:

Formula for Area :-

★ Length × Breadth ★

where,

• Length = ED = 4cm
• Breadth = DC = 7cm

➝ 4 cm × 7 cm

➝ 28 cm²

Hence, the area of Rectangle DCGE is 28cm².

3) Area of Triangle CHB:

As, we know:

Formula for Area :-

★ ½ ( base × height ) ★

where,

• Base = 3cm
• Height = 8cm

➝ ½ ( 3cm × 8cm )

➝ ½ ( 24cm )

➝ ½ × 24cm

➝ 12 cm²

Hence the Area of Triangle CHB is 12cm².

Now, Area of Given Shape is:

➝ 40cm² + 28cm² + 12cm²

➝ 52cm² + 28cm²

➝ 80cm²

Thus, the area of the given shape is 80cm².
