Question

please tell me the answer fast please​

Answer 1

Step-by-step explanation:

(1) Note:-

condition for a right triangle sum of two side of triangle must be greater than third side

Let's Check it

First side = 1.5 cm

Second Side = 2 cm

Third side = 2.5 cm

According to right triangle property :-

(i) 1.5 + 2 > 2.5

3.5> 2.5

(ii) 2+2.5 >1.5

4.5> 1.5

(iii)2.5+1.5>2

4>2

Hence verified it is right tringle

29. we have to find breadth of a rectanguler plot whose area is 440sq m and length is 22

Solution

We know that area of rectangle = L xB

than Breadth of rectangle = area/ length

$\frac{440}{22} = 20 {m}^{2} is \: breadth \: of \: plot$

Answer 2

Answer:

let length of rectangular plot is l and breadth be b

given:

area of rectangular plot= 440m^2

length= 22m

then area of rectangular plot = l×b

440 = 22× b

b = 20

perimeter of rectangular plot = 2(l+b)

= 2(22+20)

=2×42=84
