Question

find the area and perimeter of rectangle whose length is 5.7 cm and breadth is 3cm.​

Answer 1

Answer:

Area= 17.1

Perimeter= 17.4cm

Step-by-step explanation:

Area⏬⏬⏬

Length of the rectangle = 5.7cm

The breadth of the rectangle = 3cm

Area = length× breadth

.°. The area is length × height = 5.7×3 = 17.1 cm.

Perimeter ⏬⏬⏬

Length of the rectangle = 5.7cm

Length of the rectangle = 5.7cmThe breadth of the rectangle = 3cm

Perimeter of rectangle = 2×sides

= 5.7+3+5.7+3cm

= 17.4cm

Answer 2

Given:

↬length is 5.7 cm and breadth is 3cm.

To Find:

find the area and perimeter of rectangle.

Solution:

$\sf {\red{ \underbrace{perimeter : 2(length + breadth)}}}$

let's start:

$\sf : ⟹perimeter = 2(l + b) \: \: \: \\ \\ \sf : ⟹perimeter = 2(5.7 + 3) \\ \\ \sf : ⟹perimeter = 2 \times 8.7cm \\ \\ \sf : ⟹perimeter = 17.4cm \: \: \: \: \: \:$

$\blue{ \underline{ \boxed{ \pink{ \mathfrak{ \therefore \: perimeter \: of \: the \: figure = 17.4cm}}}}}$

__________________________________________

$\sf {\red{ \underbrace{area : length \times breadth}}}$

$\sf : ⟹area = length \times breadth \\ \\ \sf : ⟹area = 5.7 \times 3cm \: \: \: \: \: \: \: \: \: \: \: \\ \\ \sf : ⟹area = 17.1cm \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

$\blue{ \underline{ \boxed{ \pink{ \mathfrak{ \therefore \:area\: of \: the \: figure = 17.1cm}}}}}$
