1 The formula for the area of a triangle is A = 1/2 bh

where b is the base of the triangle and h is the height of the triangle.

What is the length of the base if the area is 22 cm2 and the height 2 is 8 cm?

The formula of area of triangle= ½ base×height

5.5cm

Step-by-step explanation:

22= (1/2)(8)(b)

22=(4)(b)

22/4= 5.5

b=5.5

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

b
