Question

1.A table top measure 2 m 25 cm by 1 m 50cm. find it's perimeter and area​

Answer 1

║⊕ANSWER⊕║

Assume,

The length of the table top = 225 cm

Breadth of the table top = 150 cm

Perimeter of the table top =

$2* (Length + Breadth)\\= 2 * (225 + 150)\\= 2 * 375\\= 750 cm$

Area of the table top =

$Length * Breadth\\= 225 * 150 \\= 33750 cm^{2}$

∴The area and perimeter of the table top is 33750 cm² and 750 cm respectively.

Answer 2

Answer: 750cm , 33750cm²

Step-by-step explanation:

Given,

measure of table top is 2m25cm  by 1m50cm  that is  length and breadth.

L = 2 m + 25cm

B = 1m + 50cm

We know that

1m = 100 cm

2m = 100 × 2 = 200 cm

Thus,

L = 200cm + 25cm = 225cm

B = 100cm + 50cm = 150cm

Now,

Area of Rectangle = Length × Breadth

                               = 225cm × 150cm

                               = 33750 cm²

Perimeter of Rectangle = 2(L + B)

                                        = 2(225 + 150)

                                        = 2 × 375

                                        = 750 cm
