In 1906, San Francisco felt the impact of an earthquake with a magnitude of 7.8.

Claimed statement is he worst is yet to come, with an earthquake 142,990 times as intense as the 1906 earthquake ready to hit San Francisco.

We need to find the magnitude of their claimed earthquake.

It can be calculated by simply multiplying 142,990 by 7.8 as follows :

$E=142990 \times 7.8\\\\=1115322$

The magnitude of claimed earthquake is 1115322 .

A neighborhood was given a vacant lot in the shape of a rectangle on which to build a park. The base of the lot is 72.2 feet and

Darya [45]

Answer:

We are given a rectangular lot with dimensions 72.2 feet long and 50 feet wide.

1. To find the size of the park, we need to find the AREA of the rectangular lot.

Area of a rectangle = Length × Width

i.e. Area of a lot = 72.2 × 50

i.e. Area of a lot = 3610 feet²

Thus, the size of the park is 3610 feet².

2. To find the amount of fencing needed, we need to find the PERIMETER of the rectangular lot.

Perimeter of rectangle = 2 × ( Length + Width )

i.e. Perimeter of the lot = 2 × ( 72.2 + 50 )

i.e. Perimeter of the lot = 2 × 122.2

i.e. Perimeter of the lot = 244.4 feet.

Thus, the amount of fencing needed for the park of the park is 244.4 feet.
