Question

3. Perimeter of a rectangle is 34cm. If its breadth is of 5 cm, find the length of
each diagonal of it?​

Answer 1

Step-by-step explanation:

B-5 cm

Perimeter - 34 cm

P - 2*(l+b)

34 - 2*(l+5)

2l+10 - 34

2l - 24

l - 12 cm

diagonal - √l^2+b^2

√12^2+5^2

√144+25=√169 =13 cm

Answer 2

Step-by-step explanation:

2(l+b)=34cm

2(L+5)=34cm

L+5=17cm

L=12cm

As we know that,

(L)^2+(b)^2=(D)^2

(5)^2+(12)^2=D^2

25+144=(D)^2

169=(D)^2

D=√169

D=13cm
