The Perimeter of a rectangular sheet is 100cm. if the length is 35 cm. find its breadth. also find the area.

$\huge{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

$\sf\green{Given :}$

➣ Perimeter of the Rectangular Sheet = 100 cm

➣ Length of Rectangular Sheet = 35 cm

$\sf\red{To \: Find :}$

➣ Breadth of the Rectangular Sheet

➣ Area of the Rectangular Sheet

$\sf\pink{Solution :}$

➪ Perimeter = 2(Length + Breadth)

⟼ 100 = 2(35 + b)

⟼ 100 = 2 × 35 + 2 × b

⟼ 100 = 70 + 2b

⟼ 2b = 100 - 70

⟼ 2b = 30

⟼ b = $\cancel\frac{30}{2}$

⟼ b = 15 cm

➦ So, Breadth of the Rectangular Sheet = 15 cm

➙ Area = Length × Breadth

⇒ Area = 35 × 15

⇒ Area = 525 cm²

➦ So, the Breadth of the Rectangular Sheet is 15 cm and the Area of the Rectangular Sheet is 525 cm²

Answer 2

the Breadth of the Rectangular Sheet is 15 cm and the Area of the Rectangular Sheet is 525 cm²...
