Question

a lawn is in the shape of a parralleogram the base is 50m and the height is 18m.you can plant 15 square meteres of grass per minute. how long will it take you to plant the lawn.

Answer 1

Given :-

◉ A lawn is in the shape of a Parallelogram, where

• Base = 50 m
• Height = 18 m

◉ It takes 1 minute to plant grass on 15 m².

To Find :-

◉ Time taken to plant on the lawn

Solution :-

We know,

⇒ Area of a Parallelogram = Base × Height

⇒ Area = 50 × 18

⇒ Area = 900 m²

Now,

Time taken to plant grass on 15 m² = 1 minute

∴ Time taken = Area / 15

⇒ Time taken = 900 / 15

⇒ Time taken = 60

Hence, It would take 60 minutes or 1 Hour to plant on the given lawn.

Some Information :-

☛ Area of Parallelogram = Base × Height

If given its base and height.

☛ Properties of Parallelogram :-

• Opposite angles are equal.
• Opposite sides are equal and parallel to each other.
• Sum of adjacent angles is 180°

Answer 2

Required answer:

ㅤ

Given:

A lawn is in the shape of a paralleogram the base is 50m and the height is 18m. You can plant 15 square metres of grass per minute.

ㅤ

Find:

How long will it take you to plant the lawn.

ㅤ

We can use the below formula to solve this question:

★ ${\boxed{\rm{Area \: of \: Parallelogram = Base \times Height}}}$

ㅤ

Calculations:

$\longrightarrow\rm{50 \times 18}$

ㅤ

$\longrightarrow\rm{900 \: m^{2}}$

Therefore, 900 m² is the area.

ㅤ

$\longrightarrow\rm{\dfrac{900}{15}}$

ㅤ

$\longrightarrow\rm{60 \: seconds}$

ㅤ

Note:

• 1 minutes = 60 Seconds.

ㅤ

Therefore, 1 minute is the required time taken.
