If l is 30 units long and w is 10 units long, how long is the diagonal to the nearest tenth.

the length of the diagonal is 31.6 units

Step-by-step explanation:

The triangle formed by the length, width and diagonal of the rectangle is a right angle triangle.

To determine the length of the diagonal, d, we would apply Pythagoras theorem which is expressed as

Hypotenuse^2 = opposite side ^2 + adjacent side^2

From the information given

Opposite side = W = 10 units

Adjacent side = L = 30 units

Hypotenuse = diagonal = d units

Therefore,

d^2 = 10^2 + 30^2

d^2 = 100 + 900

d^2 = 1000

d = √1000

d = 31.6 units

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

equal to
