Question

Find the area of iron rod of length 2m 30cm and breadth 1m 20cm mention the area in square metre

Answer 1

Step-by-step explanation:

22 metre 30 cm is equals to 230 cm that is length and breadth is 1m 20 cm is equals to 120 CM so the area equals to length * breadth therefore area equals to 230 cm into 120 CM is equals to 27600 CM square

Answer 2

Area of the iron rod = 2.76 square meter

Solution:

Given data:

Length of the iron rod = 2 m 30 cm

Breadth of the iron rod = 1 m 20 cm

Let us convert cm into m.

Note:

1 m = 100 cm

Length of the iron rod = 2 m 30 cm

                                     $=2\text{ m}+\frac{30}{100} \text{ m}$

                                     = 2.30 m

Breadth of the iron rod = 1 m 20 cm

                                     $=1\text{ m}+\frac{20}{100} \text{ m}$

                                     = 1.20 m

Area of the iron rod = length × breadth

                                 = 2.30 m × 1.20 m

                                 = 2.76 square meter

Area of the iron rod = 2.76 square meter
