Answer 1

Answer:

9

Step-by-step explanation:

we know that

area of triangle=length×breadth

360 =length×40

length=360/40

length=9 cm

Answer 2

✬ Length = 9 cm ✬

Step-by-step explanation:

Given:

• Area of rectangular piece of cardboard is 360 cm².
• Measure of breadth of cardboard is 40 cm.

To Find:

• What is the measure of length of cardboard?

Solution: Let the length of cardboard be l cm.

As we know that

★ Area of Rectangle = Length $\times$ Breadth★

A/q

• Area = 360

$\implies{\rm }$ 360 = L $\times$ 40

$\implies{\rm }$ 360 = 40L

$\implies{\rm }$ 360/40 = L

$\implies{\rm }$ 9 = L

Hence, the meaure of length is L = 9 cm
