Given area of square field =0.25 hectare
1 hectare =10,000m =0.25×10,000 =0.25×100 =2500 sq. m
Let side of square be 'a'
Area of square =a 2 a 2 =2500 ⇒a=50m
Diagonal of square = 2 a= 2 ×50=50 2 m.

What is the perimeter of a parallelogram with base 32 cm, side length 34 cm, and height 19 cm?

Serjik [45]

Answer:

$p=132cm^2$

Step-by-step explanation:

Given the following question:

Formula for perimeter:

$2(s+b)$

We are given a base and a length for this parallelogram. So, to find the perimeter we simply have to substitute the values into the formula and solve.

$2(s+b)$
$2(34+32)$
$34+32=66$
$2(66)$
$2(66)=2\times66=132$
$p=132cm^2$

Hope this helps.
