Find the area and perimeter

spin [16.1K]

Answer:

area (A) =(9x+108)unit^2

perimeter (P) =(2x+42) units

Step-by-step explanation:

area(A) =length(l) × breadth(b)

perimeter(P) =2(l+ b) {which is sum of all sides}

so, l = 7+x+5 = (x+12) units and b = 9 units

now, A=(x+12) × 9 units^2

=(9×x + 12×9 ) units^2

Therefore,

A =(9x+108)unit^2

next, P=2{(x+12)+9}

=2(x+21)

Hence,

P=(2x+42) units

The intensity of an earthquake with a magnitude of 2 is how many times greater than the intensity of an a standard earthquake ?

Ksju [112]

Answer:

The intensity of an earthquake with a magnitude of 2 is 100 times greater than the intensity of a standard earthquake.

Explanation:

The magnitude of earthquakes is given by

$Magnitude=log\frac{I}{S}$

$2=log\frac{I}{S}\\$

Where I is the intensity of earthquake and S is the intensity of standard earthquake.

The magnitude of standard earthquakes is given by

$Magnitude=log\frac{S}{S}= log(1) = 0$

So comparing the magnitude of the given earthquake and standard earthquake,

$log\frac{I}{S} = log\frac{S}{S}$

$log\frac{I}{S} - log\frac{S}{S}$

$log(2) - log(1)$

$2 - 0$

$2$

which means that

$10^2 = 100$ times greater

Therefore, the intensity of an earthquake with a magnitude of 2 is 100 times greater than the intensity of a standard earthquake.
