the length and breadth of a rectangular plot is in the ratio of 4:3. if the perimeter is 140m, find the length and breadth of a rectangle

l = 40 m and b = 30 m

Step-by-step explanation:

Let the length and breadth of a rectangle be 4x and 3x.

We know that,

The perimeter of a rectangle is given by :

P = 2(l+b)

140 = 2(4x+3x)

70 = 7x

x = 10

Length, l = 4x = 4(10) = 40 m

Breadth, b = 3x= 3(10) = 30 m

So, the length and breadth of a rectangle are 40 m and 30 m respectively.

answer: haha (: i’ll go see what it is

step-by-step explanation:

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
