Ответ:
Length of a wire = 40 cm.
Breadth of the rectangle formed = 8 cm.
Find:length and area of rectangle.
Solution:Length of a wire = 40 cm.
A rectangle is made from this wire.
That means,
Perimeter of the rectangle formed = length of the wire.
Also,
Breadth of the rectangle formed = 8 cm.
We know that,
Perimeter of a rectangle = 2(length + breadth).
Let the length of the rectangle be x cm.
Hence,
→ 2(x + 8) = 40
→ 2x + 16 = 40
→ 2x = 40 - 16
→ 2x = 24
→ x = 24/2
→ x = 12
Hence,
Length of the rectangle formed = x = 12 cm.
Now,
We know,
Area of a rectangle =length * breadth
→ Area of the rectangle = (12) * (8)
→ Area of the rectangle = 96 cm²
Therefore, the area of the rectangle formed is 96 cm².
I hope it will help you.
Regards.
