Question

(3 MA KRS EACH
A rectangular piece of land measure 0.5km by 0.8km. Each side to be fenced
with five rows of wire. What is the length of wire needed? help please please​

Answer 1

Answer:

perimeter of rectangular land = 2(l+b)

= 2(0.5+0.8)

= 2×1.3

=2.6 KM

length required for five row= 5×2.6

=13KM Ans.

Answer 2

Answer:

13 km is the length of the wire needed.

Explanation:

Length of the rectangle = 0.8 km

Breath of the rectangle = 0.5 km

Perimeter of the rectangle = 2 ( length + breath )

Perimeter = 2( 0.8 km + 0.5 km )

Perimeter = 2 ( 1.3 km )

Perimeter = 2.6 km

Each side is to be fences 5 times with wire.

Required length of wire:

= 5 × 2.6 km

= 13 km

More:

A rectangle is quadrilateral with each interior angle of measure 90°, The opposite sides of a rectangle are congruent.

Area of a rectangle = length × breath

Perimeter of a rectangle = 2 ( length + breath )
