Question

Is it possible to design a rectangular mango grove whose length is twice its breadth, and area is 800 m2? If so, find its length and breadth.

Answer 1

Answer:

let breadth be a. Then length will be 2a

Area= a×2a

= 2a²= 800

Or a²= 800/2

= 400

so. a=√400=20

Lengh= 40 m

breadth=20 m

Step-by-step explanation:

Answer 2

$\Huge{\red{\underline{\textsf{Answer}}}}$

• Let Breadth = b

• Given that length is twice it's Breadth.

• Length of reactangel = 2b.

• And given that area of reactangel = 800 m²

• But area of reactangel = l × b = b × 2b

$\rule{300}3$

$\leadsto$ 2b² = 800 m²

$\leadsto$ b² = 400 m²

$\leadsto$ b = 20 m

$\rule{300}3$

$\therefore$$\large{\blue{\underline{\tt{Length\:of\:the\: reactangel}}}}$ = $\large{\green{\underline{\tt{40m}}}}$

$\large{\purple{\underline{\tt{Breadth\:of\:the\: reactangel}}}}$ = $\large{\pink{\underline{\tt{20m}}}}$

$\therefore$It is possible to design a reactangular mango grove.
