The cover of a textbook is 9x11 inches. what is the ratio of its base to its height? does the cover of the textbook represent a golden triangle?

Hello! By "golden triangle," you likely meant "golden rectangle."

The length of a golden rectangle is appox 1.618 the width.

On the other hand, the dimensions 9 by 11 boil down to 1.222; this means that the length is approx. 1.222 times the width.

No, the textbook does not have the proportions of a golden rectangle.

b or 2, just plug these equations into your graphing calculator then check the graph to see the image. if it matches up then that's your answer!

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
