Question

find the area of adjacent figure where a is equals to 140 CM cm equals to 80 cm equals to 70 cm and a m equals to 40 cm ​

Answer 1

The area of adjacent figure where a is equals to 140 CM cm equals to 80 cm equals to 70 cm and a m equals to 40 cm .

• From given data, it is clear that, the object is not a regular polygon.
• It's a combination of ​polygons.
• Considering the given lengths of sides, let,
• AB = 140 cm
• BC = 70 cm
• AD = 80 cm
• EF = 40 cm.
• The calculation is based on the below figure attached.
• Construction: Join GF.
• Area of adjacent figure
• = area of rectangle ADEG + area of rectangle BCGF
• = 80 * 100 + 40 * 70
• = 8000 + 2800
• = 10,800 sq. cm

Answer 2

Answer:

The Area of figure is 10800 cm² .

Step-by-step explanation:

Given as :

The figure is as shown

The measure of side AB = 140 cm

The measure of side AD = 80 cm

The measure of side BC = 70 cm

The measure of side FC = 40 cm

So, The measure of side AG = 140 - 40 = 100 cm

According to figure

ADEG is rectangle and FGCB is rectangle

So, The Area of figure = Area of rectangle ADEG + Area of rectangle FGCB

i.e The Area of figure = AG × AD + BC × FC

Or, The Area of figure = 100 cm × 80 cm + 70 cm × 40 cm

Or, The Area of figure = 8000 cm² + 2800 cm²

∴ The Area of figure = 10800 cm²

Hence, The Area of figure is 10800 cm² . Answer
