Question

please right answers only​

Answer 1

Step-by-step explanation:

1. b. area of the square = side² = 49

a. let us assume side of new triangle before increase be x cm.

then , side after increase = (x+1)

2. a. let us assume 2 consecutive numbers be x and (x+1)

b. product of 2 consecutive numbers = x(x+1) = 156

here, I have taken (x+1) as the other number. you can take (x-1) as well.

3. perimeter of rectangle = 24cm

area of rectangle = 20cm²

a. half of perimeter = 24*1/2 = 12cm

b. if breadth of rectangle = x, then length will be = 20/x or (24-2x)/2

c. length * breadth = area of rectangle.

since the question does not want us to find the value of x, I have only written equations.me if you need values as well...
