Question

8. Find the length of eac side of the square when perimeter is as given below.
(b) 69 m
(c) 92 cm
(a) 42 dm
​

Answer 1

Answer:

Perimeter of square= 4*s

Step-by-step explanation:

a) 4*s=42

s=42÷4

s=1.5dm

b) 4*s=69

s=69÷4

s=17.25m

c)4*s=92

s=92÷4

s=23cm

Answer 2

$\huge\bold\pink{\mathtt{Question⇒}}$

Find the length of each side of the square when perimeter is as given below.

(a) 69 m

(b) 92 cm

(c) 42 dm

$\huge\bold\pink{\mathtt{To\:find⇒}}$

The length of the sides.

$\huge\bold\pink{\mathtt{Rule⇒}}$

$\blue{\boxed{\purple{Perimeter\:of\:square = 4a}}}$

$\green{Where,\:a\:is\:the\:side.}$

$\huge\bold\pink{\mathtt{Solution⇒}}$

(a) 69 m

Perimeter = 69 m

Let side be a m.

$4a = 69$

$➳\:a = ({\frac{69}{4}})$

$➳\:a = 17.25$

∴ Length of side = a m = 17.25 m

(b) 92 cm

Perimeter = 92 cm

Let side be a cm.

$4a = 92$

$➳\:a = ({\frac{92}{4}})$

$➳\:a = 23$

∴ Length of side = a cm = 23 cm

(c) 42 dm

Perimeter = 42 dm

Let side be a dm.

$4a = 42$

$➳\:a = ({\frac{42}{4}})$

$➳\:a = 10.5$

∴ Length of side = a dm = 10.5 dm
