Answer:

The length of each side of the triangle is 6.5 cm

Step-by-step explanation:

Perimeter of a triangle (p) = 2a + b

where a = length of side

          b = base of the triangle

        p = 20 cm

        b = 7 cm

p = 2a +b

20 = 2a + 7

2a = 20 - 7

2a = 13

a = 13 /2

a = 6.5

a = 6.5 cm

since it is an isosceles triangle, the two sides are equal = 6.5 cm

Area of the plot = 193 sq.yd.  , Option B is the correct answer.

<h3>What is Area ?</h3>

Area is the space occupied by a flat surface or an object .

It is measured in square units

It has wide daily life importance like in the question mentioned , a plot will be measured in area of the space.

It is given that

A developer buys an empty lot to build a small house.

area of the lot = ?

The figure is incomplete and the complete figure is attached with the answer.

To determine the area the figure needs to be divided into triangles and rectangles as shown in the figure

Area of the first triangle = (1/2) * base * height

By Calculation

base = 17 unit and height = 10 unit

= (1/2) * 17 * 10

= 17*5

=85 sq.unit

Area of the second triangle = (1/2)* 9* 8

=36 sq. unit

Area of the rectangle = base * height

base = 9 unit and height = 7 unit

Area = 9*7= 63 sq.unit

Area of the last triangle = (1/2) * 2*9

= 9 unit

The area of the plot = 85+36+63+9

Area of the plot = 193 sq.yd.

Therefore , Option B is the correct answer.

Find the value of X.
klemol [59]

Answer:

I think answer is 3

Step-by-step explanation:

BD = DA

BE = EC

Now, BD/BE = DA/EC

or, x + 5/2x = 4/3

or, 3x + 15 = 8x

or, 15 = 8x - 3x

or, 15 = 5x

or, 15/5 = x

or, 3 = x

Therefore x = 3 <u>Ans</u>
